Own a samsung m30s and from few weeks almost 30% of screen frombottom of phone is turned black. Nothing is visible. At times screen flickers and sometimes partial visible.

Tried basics like, updating sw, reset settings, safe mode, nothing worked so far.

Anyone faced similar issues or way to get it done?

Phone has not fallen and no damage to phone.

Maybe it was pressed. 90% display is kaput 10% mobo. Get it replaced since it should be in warranty, though it will be hard to convince them that it is not a case of physical damage.

any softwares or internal feature to check core temperature at the time of such issues?

any thick case or cover while in continued use and held in hand for long?

do not really know of their mid-rangers, M series but as @billubakra pointed out, it is rather hard to fathom the reason unless it is some assembly fault or subsequent damage, shock (falls).
(as they are not so poorly designed for them to have such issues).

Perhaps display is dying, or maybe some data lines of flex cable attached to display are broken. It would be easy for me to guess if you had shared a photo of display. You should get it replaced. Samsung M30 has super amoled display which will cost you nearly 4-5K if you get it from Samsung care. For cut corner, you go for duplicate display (IPS/TFT not Super Amoled) that will cost you under 2K. Drawback of duplicate display: No gorilla glass protection makes the display prone to break easily on falling, faded colors & dull brightness, sometime touch are not that responsive.

More than 15months so no warranty I suppose. Had Bought from amazon.

For sw issues, will try one more time factory reset.

Will this get exchanged? Sometimes black screens opacity goes very low and can see everything bt just fine line visible. After sometime, that 30% part goes completely back.

You should have contacted the Ching pang chong’s in South Korea. The franchisee’s are mostly harami.

You should do something now if it happened not long ago.

Black screens usually indicate more of a h/w issue due to misuse, because the Display was pressed… Could be due to the connector or flex too… but better to replace the complete DIsplay kit with the digitizer and all…

try this ##INFO## and then see if you find a display test and run it, if that’s faulty too, you’re looking at a hardware issue..

If you usually keep your phone in your back pocket in a jean and you wear tight jeans, could be the reason… the PCB being bent and all..

never came across such…
and putting it in the dialler changes the alphabets (INFO) to corresponding numbers, and the code becomes ★#★#4636#★#★ (and does not activate any service menu).


Samsung phones do have ★#0★#, ★#7353# though (besides other codes) to access certain diagnostic tools/ service menu options.
